Sight information auxiliary navigation direction prompting system and method thereof

The invention relates to a navigation direction prompt, in particular to a method for assisting a navigation direction prompt by using a Point of Interest (POI) information, which mainly obtains a POI of a current traveling section or a preparatory driving section, and prompts in a broadcast navigation direction (left bend, In the case of right-handed and straight-forward, in addition to the original prompting method, a POI message with a prominent signboard is added, and these messages are broadcasted in a voice or multimedia image to avoid the user from deviating from the planned path, and correctly and quickly. Lead the user to their destination.

The traditional navigation system uses the map to guide the information of the car. Recently, the 3D intersection real map has become the auxiliary information of the navigation system. These intersection maps are usually displayed when passing through expressways, viaducts, highways, etc., or complex terrain. Drivers The travel message must be obtained by the way the eyes are viewed, which tends to distract the driver's concentration.

The emergence of the voice navigation system has changed the way of navigation message transmission. The navigation system uses the way of broadcasting voice prompts to guide the user, and matches the existing map information, so that the user can receive the navigation more accurately and safely. News. The general voice navigation basic commands include prompts for the direction of travel (turning, left or right), off-route, and overspeed warning. These commands are pre-recorded as voice files and played during navigation. However, at complex intersections, only the left and right turn message is insufficient for the user. Therefore, the speech synthesis technology (Text To Speech (TTS) is applied in the voice broadcast function. When broadcasting the navigation voice, in addition to the basic prompt of the broadcast turn, the function of the next travel route name broadcast can be added, no matter which road name can be used. Instant broadcasts make it easier for the driver to determine which intersection to turn. Drivers who are traveling in unfamiliar cities/areas will also be unfamiliar with the name of the road. If the sign is placed in an inconspicuous place, the user will often be unable to respond and miss the intersection that should have been turned. Therefore, only the voice prompts broadcast by the road name are still insufficient for the driver.

Since most intersections often have shops or attractions located at intersections, the signs of shops or attractions are more eye-catching and easier to detect than the street signs. If the POI information of the turning intersection can be used in the voice broadcast prompt, the user is notified of the position or direction of the turn, so that the user can quickly and accurately determine which intersection to turn and reduce the offset planning path. In view of this, the present invention provides a method for prompting the navigation information of the attraction information, which utilizes the POI information of the intersection to guide the user to arrive at the destination more quickly and correctly.

In order to achieve the above object, the present invention discloses an attraction information-assisted navigation direction prompting system, which comprises: an electronic map module, a POI video and audio multimedia database, a voice or video broadcast module, a path planning module, and a positioning. Module, a navigation module.

2. After obtaining the starting point and the ending point, set the path planning option, and establish a set of planning results through the path planning module and display them on the electronic map. The planned navigation path information includes road information, guiding direction, distance, and POI on the planned path. News.

3. When guiding the traveling, the navigation module detects the information of the next turning intersection. When the POI data of the turning intersection is detected, the positioning module calculates the distance between the current position of the driver and the preparatory turning intersection. When the distance is within the set range, the system accesses the image data in the POI multimedia library and activates the voice or video broadcast module, and plays the pre-stored video file in the POI database to prompt the driver to prepare. What are the POIs and the direction of the turn at the corner of the turn.

4. When the driver does not set the destination, and only uses the positioning module to obtain the current location, the driver can set the POI category to be broadcasted. When the current range is within the setting range, the system will access the POI multimedia library. The image data is activated and the voice or video broadcast module is activated, and the pre-stored video file in the POI database is displayed, prompting the driver to approach the specific POI coordinate point.

Integrating the above modules and steps, the present invention utilizes an attraction information-assisted navigation direction prompting system and method thereof.
